DMulti: A function to compute multigroup dissimilarity index

Description

Multigroup dissimilarity, DMulti, is a multigroup version of Duncan's dissimilarity index (DIDuncan)

Usage

DMulti(x)

Arguments

x

- an object of class matrix (or which can be coerced to that class), where each column represents the distribution of a population group, within spatial units. The number of columns should be greater than 1 (at least 2 population groups are required). You should not include a column with total population in each unit, because this will be interpreted as a group.

Value

Multigroup dissimilarity index
